There are more than 550 active volcanoes in the world, almost all of which are located at convergent tectonic plate boundaries. This includes all of the volcanoes in the Pacific Ring of Fire, such as Japan's Mount Fuji, ... More »

Convergent boundaries are defined as locations where tectonic plates collide with each other. The melting lithospheric material produces volcanoes, and the motion of the tectonic plates along the convergent boundaries le... More »

Volcanoes are found where the tectonic places that make up the Earth's surface are either pushing together or pulling apart. They are also found away from plate boundaries at "hot spots," where magma pushes through the E... More »

Examples of volcanoes found along divergent plate boundaries include Krafla Volcano in Iceland, as well as Erta Ale and Oldoinyo Lengai in Africa. The process of volcanic formation along divergent boundaries is called sp... More »

Plate boundaries are the weakest points in the Earth's crust, which leads to cracks that allow magma to seep through and develop volcanoes, according to NEWTON. These areas are called "subduction zones." Subduction zones... More »

Volcanic arcs are formed when an oceanic plate is forced under a continental plate and the water-soaked crust melts as it's forced below the ocean floor, creating magma that feeds volcanoes on the continental side of the... More »

The three types of plate boundaries are divergent plate boundaries, convergent plate boundaries and transform plate boundaries. Divergent plate boundaries occur in places where two plates are moving away from each other.... More »
